Electric Air Furnace

Duct electric heater is mainly used for air heating in the air duct, specifications are divided into low, medium, high temperature three forms.

Introduction
Electric air furnace is mainly used to heat the air in air duct, which can be classified as low-temperature furnace, medium-temperature furnace and high-temperature furnace. What is common in the configuration is that steel plates are used to support the electrothermal tubes and the overtemperature control device is installed in the junction box. Besides, draught fan and electric heater are connected by a control device that can make sure that the heater only begin working after the start of draught fan.  Differential pressure devices are installed on both sides of heaters in case of the breakdown of draught fan. Generally, the pressure of heated air should not exceed 0.3Kg/cm2. If needed, customers should use circulating electric heater. The highest heating temperature for the above three kinds of furnaces is respectively 160℃,260℃ and 500℃.
Electric air furnaces have been widely used in the fields of aeronautics, astronautics, weapon industry and chemical engineering. Also electric air furnaces are largely needed by the laboratories in colleges and research institutes, which are especially for the experiment of united system and accessories with automatic temperature control and high-temperature mass flow.  Our electric air furnace products are applicable to all kinds of gas, of which the heated gas is fully dried, non-conductible, non-combustible, non-explosive, non-corrosive and pollution-free.  


Product Features
1. Good heating effect. The cool air can be heated to 850℃, while the shell temperature is just around 50℃.
2.High efficiency. The heating efficiency of our product is above 90%.
3.Fast heating rate and cooling rate. The temperature control is timely and steady, which could reach 10℃/S. The instability caused by delayed response can be avoided, which is suitable for automatic control.
4.Great mechanical property. The heating unit is made of special alloy materials with better mechanical properties and strength under the impact of high-pressure flow, which is a great advantage in continuous working state.
5.Long working life. If used properly, our product can last more than ten years.
6.Pollution-free and space-saving.
Our product can be customized based on your requirement (drawing, voltage, power, size).
